Troubleshooting Guidelines
This chapter lists possible malfunctions that may occur while operating a Carbon

Jam
If paper jams inside the printer:
1
Open the printer door.
2
Remove the damaged paper from the paper roll.

If the problem persists, it may be due to poor paper quality. Install a new roll of
higher-quality printer paper.
